Forgot to plug in my Eheim 1250 pump today on my 2900s loop after trying out a 3870x2, it got hot one of the hose blew off one of the cards and got everything wet. I heard it when it happened and ran and unplugged it. It was in the process of rebooting when I jerked the chord from the power supply. I got everything apart and drying, been using a hair drier also. I will put it back together tomorrow and see what happens...
